EDWIN P. FULLER, OF DETROIT, MICHIGAN.

SMOKE-FILTER.

To all whom it may concern:

Be it known that I, EDWIN P. FULLER, citizen of the United States,residing at Detroit, in the county of Vfayne and State of Michigan, haveinvented certain new and useful Improvements in Smoke-Filters, of whichthe following is a specification.

My invention is a smoke filter, its object being to provide means forseparating the soot, cinders and unconsumed material from the gases, andcondensing and discharging the gases into the smoke stack or open air;and the invention consists in the peculiar construction, arrangement andcombination of the parts.

Figure 1 is a side elevation of a furnace provided with my invention.Fig. 2 is a vertical section of the filter. Fig. 3 and Fig. 4 aredetails of parts of the filter.

In the drawings, 1 is the furnace; 2 the smoke stack; 2 a damper in thestack above the pipe 3 which extends from the stack to the filter 6,entering the filter near the bottom on a tangent 5, as shown in Fig. 2.In the pipe 3 I have located an exhaust device 4 which may be a fan orpump run at sulficient speed to create a vacuum and draw the smoke fromthe stack or the fire place as the pipe 3 may be connected direct to thefire Specification of Letters Patent.

the compartments, viz: the smaller in the first, 11 in the second, 10 inthe third, etc. and they are for the purpose, as stated, of deflectingand directing the smoke and giving it a more perfect circulation throughthe mattresses.

12 is a Water pipe extending up the side of the drum, with tubes 13leading to the center of each compartment, each rovided with a spraynozzle 14 to spray tie chamber, to wash the lower side of the mattress,and rinse off the plates, soot, cinders, etc., being washed to thebottom of the drum and out of the pipe 17 In order that the soot andnoncombustible material falling upon the upper side of the mattressesmay be removed, I provide a door to each compartment through which theaccumulations may be removed. Of y course the number of partitions,mattresses and plates may be increased or diminished according to therequired capacity of the exhaust. The damper 2 is for the purpose ofpreventing the exhaust 4 drawing the gas discharged from the filter downthe stack into the filter again. When the fire is first built thesedampers are opened until a head of steam is attained sufficient to drivethe exhaust 4 when the dam ers are closed and place, and force the smokeinto the filter 6 the smoke drawn througi the filter.

through the tangential opening 5.

7 is a pipe at the top of the filter conveying the gases to the smokestack, or it may be to the open air.

My filter 6 is a hollow chamber cylindrical I or otherwise which forconvenience I will term a drum. It is provided with a conical shapedbottom having the drip pipe 17 at the center of the depending apex. 'Ihedrum is divided into a number of compartments by one or more partitions8, preferably placed posed of fibrous matter such as asbestos or mineralWool.

10 is a conical shaped plate inverted and secured to the under side ofthe partition at Having thus described my invention, what I claim as newand desire to secure by Letters Patent is:

1. A smoke filter comprising a chamber having a tangential inlet at itslower portion, and an outlet at the top, and a series of partitionsacross the chamber, the lower partition comprising a plate having acentral opening and a mattress of fibrous material above the plate, thenext partition compris- E ing a perforated plate provided with a largehorizontally, each having a mattress 9 comcentral opening and a mattressof fibrous matter above the plate, the next partition like the lower,and so on alternating plates and mattresses to the top of the filter,and a 1sipicrlay pipe between the partitions, as speci- 2. A smokefilter comprising a chamber having a tangential inlet at its lowerportion, a series of hopper shaped plates smaller than the chamber, aseries of plates of the size of the chamber having a large centralopening, the two series of plates alternating in the chamber, a mattressof fibrous material between the plates, and a spray pipe between themattresses, as specified.

3. In a smoke filter, the combination with a drum, of a pipe leadingfrom the furnace to the drum and having a tangential entrahce to thedrum at the bottom thereof, and the discharge pipe at or near the top ofthe drum, of one or more partitions in the drum, the partitionscomprising a plate having a central opening and a mattress of fibrousmaterial a ove the plate, a spray pipe between each pair of partitions,and an exhaust device for forcing the smoke from the furnace through thefilter, substantially as specified.

4. A smoke filter comprising a chamber having a fiat top and a funnelshaped bottom provided with a drip pipe, an opening near the bottomconnected with a pipe entering the opening tangentially, a series ofmattresses across the chamber composed of fibrous matter, arranged oneabove the other, a spray pipe between each mattress and an opening atthe top of the chamber, substantially as described.

In testimony whereof, I affiX my signature in presence of two witnesses.
